Those sills aren't pretty, and it bodes poorly for the floors. I think you are making the right move in passing, at that money. It needs some serious work right now. Personally, I would much rather have a car with engine troubles and a nice body than vice versa. In time, something better will come.

If you have a bit more to throw around, there's a very pretty and very early DB334 fintail on ebay right now...garish overdyed interior (notice very rare bench seat, I've only seen this in a Universal)
